The extension can be configured if you go to Stores > Configuration and afterwards to Magenerds > Base Price.
After enabling the extension you can edit the base price template in order to influence the base price rendering in the frontend. You can type in whatever you want.
There are five variables available to render the base price information:

• {BASE_PRICE}: Renders the calculated base price

• {BASE_AMOUNT}: Renders the product sale amount

• {BASE_UNIT}: Renders the product sale unit

• {REF_AMOUNT}: Renders the reference amount

• {REF_UNIT}: Renders the reference unit

Example: {BASE_AMOUNT} {BASE_UNIT} | {BASE__PRICE} / {REF__AMOUNT} {REF__UNIT} will render to: 1 tn | 2.90€ / 10 kg

The extension install basic units and its conversions. But you can edit these conversions, delete the units or extend it with further units and its conversions.
Just click on Add below all those conversions in order to add another unit row. You define the product unit on the left side and the reference unit (the unit which the price will be calculated to) on the right side.

Every product needs detailed information about the base price calculation. There are four attributes which every product has:

• Product amount: Select the amount the product gets selled with quantity 1
• Product unit: Select the unit the product gets selled with
• Reference amount: Select the reference amount the product price has to be calculated with
• Reference unit: Select the reference unit the product price has to be calculated with

Example: You have a product which is a bottle of milk which is 100 ml of size. It costs 2 €.
You want to display the price of milk for 1 l which is 20 €.
Therefore you have to configure your product like the following:

• Product amount: 100
• Product unit: ml
• Reference amount: 1
• Reference unit: l

You can configure the attributes in a product edit mask under the tab Base Price on the left side.
